Australia's hopes of breaking a 12-year drought in New Zealand have been dealt another major blow, with wingers Joe Tomane and Chris Feauai-Sautia ruled out of the Bledisloe Cup Test against the All Blacks at Forsyth Barr Stadium in Dunedin on Saturday night.

The Wallabies had already lost centre and goalkicker Christian Leali'ifano and in-form flanker Scott Fardy, and the latest injury setbacks on the wing add to an already extensive list of wide players who are unavailable. Tomane and Feauai-Sautia both have hamstring injuries, but they are expected to be available for the opening match of the Wallabies end-of-year tour of Europe against England on November 2.

New South Wales Waratahs winger Peter Betham has been added to the Wallabies' 24-man squad for the Dunedin match, but Nick Cummins, himself returning from a broken hand, shapes as the front-runner to replace Tomane.

The injury dramas have added to selection headaches for Ewen McKenzie since he took over as Wallabies coach. McKenzie moved Adam Ashley-Cooper from outside centre to fill a void on the flanks against Argentina in Rosario, and he will have to consider shifting Israel Folau to the wing and naming Bernard Foley at fullback if Cummins is not fit to start.

Matt Toomua is set to replace Leali'ifano at No.12 and Ben McCalman tipped to come in for Fardy.
